I try to send command to switch with ansible. I tested and confirmed the switch can be accessed by other devices via ssh, but when sending command to the switch via ansible, it failed. The below is commands and error message. Anyone provide some suggestions to the issue? Thank you.
sudo nano hosts
[lab-hosts]
192.168.1.15
sudo nano ansible.cfg
[defaults]
inventory = ./hosts
host_key checking = false
timeout = 5
sudo mkdir group_vars
cd /group_vars
sudo nano devices.yml
ansible_network_os: ios
admin1@Lenovo10:~$ ansible lab-hosts -m raw -a "show run" -u admin -k | grep 'hostname| system mtu' -vvvv
SSH password:
